I Just saw it!! No link yet, of course, but Highlight was STEALTH FORCE BUMBLEBEE!!! No way!?! That was wicked!

Other new stuff:

~ Starscream transforming and confronting Sam...again
~Optimus Prime walking and "reloading" his gun where the casing comes toward the screen (good use of 3D, I'm sure)
~Sam talking with Carly
~Epps Yelling
~Voiceover work by someone. I have no idea what was said or who was talking because I was stunned that there was a new trailer...
